Question

How to Detect if the visitor is logging by mobile and turn him to index.php and when logging from PC turn him to index.html

is that by .htaccess or what?

Answer 1

You need to use some sort of information provided by the client to determine if the user is on a mobile device or not.

There any many ways to do this, for example in JavaScript

if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
    /* User is mobile... */
}

Which will check for a string used in a mobile device in the user agent.

There are libraries such as Modernizr ( http://www.modernizr.com/ ) which have things like this to help you.

All in all, there's no set way to do it - you'll have to try different methods and choose the one you like.

Answer 2

You can use these rules in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On
RewriteBase /

# forward mobile users to index.php
RewriteCond %{HTTP_ACCEPT} "text\/vnd\.wap\.wml|application\/vnd\.wap\.xhtml\+xml" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "sony|symbian|nokia|samsung|mobile|windows ce|epoc|opera" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "mini|nitro|j2me|midp-|cldc-|netfront|mot|up\.browser|up\.link|audiovox"[NC,OR]
RewriteCond %{HTTP_USER_AGENT} "blackberry|ericsson,|panasonic|philips|sanyo|sharp|sie-"[NC,OR]
RewriteCond %{HTTP_USER_AGENT} "portalmmm|blazer|avantgo|danger|palm|series60|palmsource|pocketpc"[NC,OR]
RewriteCond %{HTTP_USER_AGENT} "smartphone|rover|ipaq|au-mic,|alcatel|ericy|vodafone\/|wap1\.|wap2\.|iPhone|android"[NC]
RewriteRule ^ - [E=ISMOBILE:1]

RewriteCond %{ENV:ISMOBILE} =1
RewriteRule !^index\.php$ index.php [L]

# otherwise desktop users to index.html
RewriteCond %{ENV:ISMOBILE} !=1
RewriteRule !^index\.html$ index.html [L]

It can be done with this php script, it will return a true if mobile, some mobile user agents are missing

<?php
    // ------- DETECT USER DEVICE ----------
    $user_device = "";
    $IsMobile = "";
    $agent = $_SERVER['HTTP_USER_AGENT'];
    if (preg_match("/Valve/", $agent)) {
       $user_device = "Steam GameOverlay";
    } else if (preg_match("/Safari/", $agent)) {
        $user_device = "Safari";
    } else if (preg_match("/Android/", $agent)) {
        $user_device = "Android Mobile";
    } else if (preg_match("/IEMobile/", $agent)) {
        $user_device = "Windows Mobile";
    } else if (preg_match("/Chrome/", $agent)) {
        $user_device = "Google Chrome";
    } else if (preg_match("/MSIE/", $agent)) {
        $user_device = "Internet Explorer";
    } else if (preg_match("/Firefox/", $agent)) {
        $user_device = "Firefox";
    } else if (preg_match("/Opera/", $agent)) {
        $user_device = "Opera";
    }
    $OSList = array

    // Loop through the array of user agents and matching operating systems
    foreach($OSList as $CurrOS=>$Match) {

            if (@eregi($Match, $agent)) {
                    break;
            } else {
                $CurrOS = "Ukendt OS";

    }
    if ($user_device == ""){

    //$device = "$user_device : $CurrOS";
    $device = "$CurrOS";
    // ------- END DETECT USER DEVICE ----------

    if ($CurrOS == "Android" || $CurrOS == "Windows Phone" || $CurrOS == "iPhone"){
        $IsMobile = "True ".$CurrOS;
